Protocol

Ecosystem

The software around the chain: what the protocol has shipped, which wallets can actually use it, and how much engineering is going in. A shielded pool is only as real as the wallets that emit transactions for it.

Wallet capability matrix

What each wallet can do today. 'Unified' means it hands out unified addresses so senders need not choose a pool.

Upgrade history

Every consensus change, with the block it activated at. These are the vertical markers you see on most charts.

NU6.3 — Ironwoodupgrade#3,428,143 · 28 July 2026

A fresh shielded pool with the fixed circuit baked in, so value can be re-proven as it crosses. Orchard drains through the turnstile into it.

A value-balance flaw in the Orchard proving circuit — present since 2022 and capable of minting counterfeit shielded notes — was disclosed by Shielded Labs and patched under an emergency upgrade. ZEC fell around 38% on the news.
